Electromagnetic interference (EMI) considerations
The drive models described herein, as delivered, are designed
for system integration and installation into a suitable enclosure
prior to use. As such, the drive models described herein are
supplied as subassemblies and are not subject to Subpart J of
Part 15 of the FCC Rules and Regulations nor the Radio
Interference Regulations of the Canadian Department of Com-
munications.However, the unitshave been testedusing proper
shielding and grounding and found to be compliant with the
Class A limits of the FCC Rules and the Regulations of the
Canadian Department of Communications.

_______________________________________________________________________________________________________________________
The physical design characteristics of the drive models de-
scribed herein, serve to minimize EMI radiation when installed
inanenclosurethatprovidesreasonableshielding.Assuch,the
drive(s) are capable of meeting the Class B limits of the FCC
Rules and the Regulations of the Canadian Department of
Communications.
Note. It is the end users' responsibility to assure that the drive
models described herein meet the appropriate EMI re-
quirements of their system. Shielded I/O cables may be
required if the enclosure does not provide adequate
shielding. If I/O cables are external to the enclosure,
shieldedcablesshouldbeused,withtheshieldsgrounded
to the enclosure or to the host controller, but not both.
The equipment is designed to provide reasonable protection
against such interference in a residential installation. However,
there is no guarantee that interference will not occur in a
particularinstallation.Ifthisequipmentdoes cause interference
to radio or television, which can be determined by turning the
equipment on and off, you are encouraged to try one or more of
the following corrective measures:
• Reorient the receiving antenna.
• Move the device to one side or the other of the radio or TV.
• Plug the computer into a different AC power outlet so that the
receiverandcomputerareondifferentbranchoutlets.Thatis,
circuits controlled by different circuit breakers.
If necessary you should consult your dealer or an experienced
radio/television technician for additional suggestions.

You may need this if your computer does not already have a
hard drive, if your present drive does not connect to a SCSI
host adapter, or if your present SCSI adapter card cannot
address a drive having the capacity the Hawk 2XL has.
The host adapter card should have instructions with it for
installing the card and assist in the installation of hard disc
drives that it supports.
• A 50-pin SCSI interface cable
You will need an interface cable if your computer does not
presently contain a SCSI hard drive.If you are adding a sec-
ond hard drive you must use an interface cable that has two
drive connectors, one on the end and one in the middle.See
Figure 1.
• AY-shaped drive power cable
You may need this if your computer does not have enough
power cables to supply power to your new hard drive. See
Figure 2.
• Mounting screws

if you mount your drive directly into the drive bay.See Safety
Instructions for maximum screw length (see Figure 6).
